PrettyFormatter: Fix ArrayIndexOutOfBoundException with CRLF files.

Change I6d82ce322d401743a8de5ab8090b2adc43a909f5 added a workaround for
a bug in prettify, by temporarily adding a space before each \n
character.

For files with CRLF line endings, this means replacing "\r\n" by
"\r<space>\n", which prettify sees as two lines. This leads to a
crash since Gerrit expects a consistent number of lines even after
prettify.

When Show Line Endings is active, the issue does not appear since \r
are replaced with a specific markup, without any actual \r.
